IMPROVEMENT IN MACHINES FOR GATHERING STONES.

Specification forming part of Letters Patent No. 20,774, dated July 6,1858.

To all whom it may concern:

Be it known that I, G. W. BIsn0P,of Brook lyn, in the county of Kingsand State of New York, have invented a new and useful Device for Pickingor Gathering Stones from the Field; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the annexed drawings, making a part of this specification,inwhich- Figure 1 is a longitudinal vertical section of my invention,the plane of section passing through the center. Fig. 2 is a plan or topview of same. Fig. 3 is a detached face view of the reciprocatingscraper.

Similar letters of reference indicate corresponding parts in the severalfigures.

This invention consists in having a receptacle or box mounted on wheelsand having an inclined plane at its front end, the wheels of thereceptacle or box having rods attached, said rods being connected to ascraper which works over the inclined plane, and which scraper, by meansof springs or drop-guides, in connection with the rods aforesaid, ismade as the machine is drawn along to draw up the stones into thereceptacle or box.

To enable those skilled in the art'to fully understand and construct myinvention, I will proceed to describe it.

A represents the receptacle or box, which transversely may be ofV-shape, havingan axle, B, passing longitudinally through it at aboutits center.

0 O are the wheels of axle B.

To the front end of box A an inclined plane, I), is attached, the innerand upper end of the plane being secured to the upper end of the frontside of the box A, as shown plainly in Fig. 1. The lower end of theplane D is shod or has a metal plate, 0, attached, the edge of which isserrated, as shown clearly in Fig. 2, the plane D, as well as the box A,being of wood. At each end of the plane D there is any inclined ledge,E, the upper surfaces of which are covered or faced with metal.

F is a scraper, which is constructed of metal, and provided at each endwith a hook-shaped shank, I). (See Figs. 2 and 8.) The blade of thescraper F fits between the two ledges E E, the upper parts of theshanks 1) extending To each side of the plane D there is attachedaspring-guide, G. These guides are constructed of metal, and are ofcurved form, as shown clearly by the dotted lines in Fig. 1. Thespring-guides G are of such vidth that they may fit within the hookedshanks I). (See Fig. 2.)

To the front end of the plane D draft-hooks c are attached, one to eachside, and to each end of the scraper F a rod, H, is attached. The rods Hare connected at their opposite ends to the wheels 0, near theirperipheries.

On the upper part of the box A a seat, I, is placed; and J is afoot-rest, also placed on the box A, below the seat I.

The operation is as follows: The horse is attached to the front end ofthe plane D, the driver being on seat I. As the machine is drawn alongin the direction indicated by arrow 1 a reciprocating motion is giventhe scraper F. As the scraper is moved upward the upper parts of theshanks b rest on the upper surfaces of the ledges E E, and the loweredge of the scraper is close down to the surface of the plane. When,however, the scraper has been drawn fully upward, or as it reaches theend of its backward stroke, the lower parts of the shanks b will passabove the upper and back ends of the spring-guides G, and during thedownward or forward stroke of the scraper it is elevated above thesurface of the plane D, as shown in red, Fig. 1, the elevation beingcaused by the lower parts of the shanks resting on the top of thespring-guides Gr. As the lower parts of the shanks pass oft from thespring-guides G the scraper F falls on the ground a little in front ofthe plate a, and as it ascends or moves up the plane D all stones thatthe plate a may have scraped up at its lower end are drawn up anddeposited in the box A.

This machine will prove valuable for movin g small stones from fieldspreparatory to tilling them. Byits use the work may be rapidly done andwith a comparatively small amount of labor.

I would remark that instead of the springguides Gr drop-guides may beused. They,

however, would be equivalent to the springing scraper F andspring-guides G G, or their guides. equivalents, the whole beingarranged to op- Havin g thus described my invention, what erate as andfor the purpose set forth.

I claim as new, and desire to secure by Letters G. W. BISHOP. Patent,is- Witnesses:
